1 MK Sun



Nobeyama Radioheliograph (NoRH) can observe plasmas with temperature of 1 MK (10^6 Kelvin). This figure shows the 1993-3-16 flare. The left panel shows the soft X-ray image taken by Yohkoh satellite, and the right panel shows the 17 GHz image taken by NoRH. The loop-like structre is almost common. But detailed study indicates the intensity distributions are a little different in these images. This is because temperature is not uniform in the loop.
